Good value... but can be modified to work better by reducing the bias current on the output stage. Resistor R6 needs to be reduced. Can use a small (10k) trimpot to make adjustable.

mapetek Ezt még nem nevezném hibának, az árát figyelembe véve.Egy megfelelő előerősítő használata ajánlott. Viszont valós 100 wottos teljesítménynél ellenálások, és diódák mentek tönkre. Sőtt a tekercs is megégett. 60 Wattig talán hibátlanul működhet.

Q: What is the lowest Amp reading achievable? Specification states 6A minimum. Not that usable at 240V.
로 질문하기 BG534854401 에 2020-06-07 03:14:46
Graham From the display (XX.X) it would seem that 0.1A is the lowest... also effectively the minimum resolution of any reading
